Sierra Space’s Dream Chaser spaceplane has completed a series of critical pre-flight tests at NASA’s Kennedy Space Center, paving the way for its first uncrewed free-flyer mission.
The testing campaign included Electromagnetic Interference and Electromagnetic Compatibility tests at NASA’s Space Systems Processing Facility, confirming the spacecraft’s resilience in complex electromagnetic environments.
Dream Chaser also underwent high-speed tow trials at KSC and the Space Florida Launch and Landing Facility. A Freightliner Cascadia truck from Daimler Truck North America was used to simulate landing dynamics and verify autonomous runway navigation capabilities.
Command and telemetry systems were tested over NASA’s Tracking and Data Relay Satellite System, successfully confirming real-time link integrity between the spacecraft and Mission Control in Louisville, Colorado.
The test phase concluded with a full post-landing recovery rehearsal, including vehicle safing and prompt access to sensitive payloads.
Acoustic testing is scheduled for December 2025. After that, modifications for national security applications will be undertaken in Colorado to expand the spacecraft’s defence mission versatility.
Dream Chaser is scheduled to reach Low Earth Orbit in Q4 2026 under a CRS-2 demonstration mission with a planned landing at Vandenberg Space Force Base.
“Each milestone we achieve is a testament to the resilience, innovation and dedication of the Sierra Space team, and represents another significant step forward in ensuring Dream Chaser’s success as a versatile, reusable spacecraft,” says Sierra Space Executive Chair Fatih Ozmen.
